Evacuator® back-up alarm offers superior reliability with exceptional warning power. Evacuator alarms utilize piezo-electric circuitry and solid-state components to minimize the effects of vibration and reduce amp draw. To seal out moisture and contaminants, the unique nickel-plated terminal inserts are hermetically sealed, and the housing is environmentally sealed.
The Evacuator back-up alarm includes a dual function feature. The dual function feature allows the alarm to produce two distinctly different tones by reversing the polarity of the wiring. Normal polarity produces a “Pulsed” tone, which is an intermittent signal that is primarily use for back-up warning. Reversed polarity produces a “Constant-On” tone, which is a continuous signal that can be used to signal motion such as the lifting of a truck platform or gate.
